Big Idea 1 ? Evolution Exam Campbell-Reece 8th Edition ? Chapters 22-26 Name: _________________________________ Date: __________________ Multiple Choice (1pts each; TOTAL = 37 pts) Read each question carefully and choose the BEST answer. WRITE ALL ANSWERS ON THE ANSWER SHEET Your friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks? Which statement is the best response to correct your friend?s misconception? Overproduction of offspring leads to a struggle for survival. Only favorable adaptations have survival value. Characteristics acquired during an organism's life are generally not passed on through genes to its offspring. Disuse of an organ may lead to its eventual disappearance.
